An illegal immigrant on a Greyhound bus who allegedly threatened to shoot and kill passengers on Friday — leading police on a chase from Wisconsin to Illinois — was deported five times, a U.S. Customs and Border Protection spokesperson told Fox News.

The spokesperson said on Sunday that Margarito Vargas-Rosas, 33, who faces terror charges, was in the U.S. illegally and was "removed" from the U.S. the last five times Border Patrol agents encountered him. He also had a previous DUI arrest to his name.

A judge in Illinois on Sunday ordered the suspect held without bond. Vargas-Rosas faces a fugitive-from-justice charge.
